It played a major role in the history of astronomy and navigation , and because
234-525: A garrison to guard the Tower; by the early 17th century this had been formalised into a standing militia . During the reign of Charles II , the Tower was still consistently being guarded by two garrison companies of militia. Then in 1685, following Charles's death, the new King James II asked Lord Dartmouth (who was Constable of the Tower at the time, as well as Master-general of the Ordnance) to form
351-597: A Board of Visitors, founded in 1710 and made up of the President and Members of the council of the Royal Society. By the later 18th century it incorporated additional responsibilities such as publishing the Nautical Almanac , advising government on technical matters, disseminating time, making meteorological and magnetic observations and undertaking astrophotography and spectroscopy. The physical site and

The Arms of the Board of Ordnance first appeared in the seventeenth century, and were given royal approval in 1806, confirmed by a grant from the College of Arms in 1823. The blazon is as follows: The old Board's coat of arms is remembered today in the cap badge of the Royal Logistic Corps , which has
585-829: A central Grand Storehouse (primarily used for gun carriages). Exterior courtyards were laid out for the storage of cannonballs. The principal home Yards included: Smaller Yards were built in parts of Britain to serve particular strategic purposes at particular times (such as the Yard in Great Yarmouth , built to service the fleet stationed in Yarmouth Roads during the Napoleonic Wars ). Ordnance Yards were also constructed in colonial ports overseas; like their counterparts in Britain, these were usually built in

The Board's administrative staff had expanded during the Napoleonic Wars to such an extent that in 1806 it purchased the lease of Cumberland House in Pall Mall and moved its main offices there, subsequently expanding into neighbouring properties. The Board itself also began to hold its meetings there, in preference to the Tower or Woolwich or other locations where it had previously been accustomed to meet. At
819-562: A further ten companies of 100 men each (again drafted from the Tower Hamlets ); there was in addition a company of miners . The regiment was to be housed in the Grand Storehouse, then under construction in the Tower. As a precaution against the risk of igniting the Ordnance stores of gunpowder, it was equipped with modern flintlock fusils, rather than with the matchlock muskets borne by most other regular troops. As such,
936-590: A guard. 1793 saw the formation of the Royal Horse Artillery (who were likewise under the authority of the Board of Ordnance) to provide artillery support to the Cavalry. From the start, the Board (and its predecessor the Office) of Ordnance had had a department of military engineers and surveyors to build and improve harbours, forts and other fortifications. In 1716 a Corps of Engineers was founded by
1053-698: A gunsmith, produced long guns for the Tower's small arms office in the 1780s. From the mid-17th century the Board of Ordnance began to be involved in the design, building and upkeep of forts, fortifications and various garrison buildings. Around the year 1635, a Francis Coningsby was appointed 'Commissary-General of all His Majesty's Castles in England and Wales'. From 1660 the title was Engineer-in-Chief. The Chief Engineer had responsibility for drawing up designs, supervising site surveys and building works, and visiting established defence sites to evaluate their state of repair, readiness etc. An illustrious holder of this post
1170-739: A higher spot with better weather. On 1 December 1967, the Isaac Newton Telescope of the Royal Greenwich Observatory at Herstmonceux was inaugurated by Queen Elizabeth II. The telescope was the biggest telescope by aperture in the British Isles. It was moved to Roque de los Muchachos Observatory in Spain's Canary Islands in 1979. In 1990 the RGO moved to Cambridge . At Herstmonceux, the castle grounds became

The old guard companies formed the core of this new regiment, but they were soon augmented by
1521-519: A new complex at Bull Point (where it was integrated with a nearby proofing and purifying facility) - this proved to be the last major construction project of the Board of Ordnance before its disestablishment. The Board of Ordnance was responsible, throughout its existence, for supplying the Army and Navy with weapons and ammunition. Other items were provided by various other boards and agencies (or, in earlier times, by private contractors). From 1822, however,
1638-608: A noted tourist and education attraction in its own right, featuring many old observatory items as exhibits. It was getting 60,000 visitors per year in the early 21st century. In 1990 the Royal Observatory moved from Herstmonceux to a new site at Cambridge , adjacent to the University 's Institute of Astronomy , where it occupied Greenwich House just to the north of the Cambridge Observatory . By now,
1755-502: A period of four seconds and an accuracy, then unparalleled, of seven seconds per day. The original observatory housed the astronomer royal, his assistant and his family as well as the scientific instruments to be used by Flamsteed in his work on stellar tables. Over time the institution became a more established institution, thanks to its links to long-lasting government boards (the Board of Ordnance and Board of Longitude ) and oversight by
1872-512: A plan to have better instruments at Greenwich observatory. Positional astronomy was one of the primary functions of Greenwich for the Admiralty. The Astronomer Royal Airy was an advocate of this and the transit circle instrument he had installed in 1851 was used for a century for positional astronomy. One of the difficulties with positional astronomy, is accounting for the refraction of light through Earth's atmosphere . Sources of error include

In the wake of the French Revolution , however, there was a spate of barrack building and the new post of Barrackmaster-General was established to oversee it; he was answerable not to the Board of Ordnance but to the Secretary at War . (The Board, though, retained responsibility for providing and provisioning barracks for its own corps). Apparent mismanagement in

In 1949, the regimental depot (which had been located in Hounslow Barracks since 1873) returned to the Tower, to Waterloo Barracks (which had been built on the site of the old Grand Storehouse following a fire); it remained there for the next eleven years. Today,
2223-428: A sample from each batch was proof tested . This took place in one of a pair of smaller buildings alongside and linked to the main magazine (which was a windowless quadrangle). Very soon, however, the Board was coming under pressure from local residents to remove the gunpowder store from Greenwich. Eventually, in 1763, a new set of magazines were built, along with a new proof-house, further downriver at Purfleet . Named
2340-605: A waterway, it was connected to the Grand Union Canal to facilitate access and distribution. At the same time a similar (but short-lived) facility was also built alongside the Grand Junction Canal at North Hyde , west of London. The Board established storage and maintenance areas close to the Royal Dockyards to enable easy transfer of guns, ammunition, powder, etc. on board ships (for use by

There were also smaller magazines, supervised by Ordnance Board staff, at several fortified locations around the British Isles (from Star Castle on the Scilly Isles , to Fort George near Inverness ). The Tower of London remained

The Master-General was head of both Establishments; on a practical level, the Lieutenant-General had day-to-day oversight of the military personnel and the Surveyor-General oversaw the civil departments. From its earliest years, the Ordnance Office was staffed by

They were not part of the Army, and their officers' commissions were issued by the Master-General of the Ordnance rather than by the Commander-in-Chief of the Forces . The Ordnance Medical Department was established to provide surgeons for these corps. In 1716

The Board lasted until 1855, at which point (tarnished by poor performance in supplying the Army in Crimea ) it was disbanded. The introduction of gunpowder to Europe led to innovations in offensive weapons, such as cannon, and defences, such as fortifications. From

8775-532: The influence of the Privy Wardrobe and its staff receded, and no new Keepers were appointed after 1476. In its place, a distinct Office of Ordnance began to establish itself at the Tower; this body was responsible for firearms and artillery, and was staffed in the 1460s by a Master, a Clerk and a Yeoman. In the 1540s, during the reign of Henry VIII , the Ordnance Office was expanded, with new officers appointed and their principal duties clarified. In 1671,
8892-541: The library, and observing equipment. The largest telescope at Greenwich at that time, the Yapp telescope 36-inch reflector, was moved out to Herstmonceux in 1958. There it was reconstructed in Dome B of the facility. There it was used for astronomy in the 1960s, 1970s, and 1980s. It was left behind at Herstmonceux in 1990 in its dome when the organization moved once again. The tricentennial of Sir Isaac Newton had passed during
9009-474: The main facility. The Observatory underwent an attempted bombing on 15 February 1894. This was possibly the first "international terrorist" incident in Britain. The bomb was accidentally detonated while being held by 26-year-old French anarchist Martial Bourdin in Greenwich Park , near the Observatory building. Bourdin died about 30 minutes later. It is not known why he chose the observatory, or whether
9126-525: The main repository, and it remained the administrative centre of the new Board. Gunpowder was stored in the White Tower (and continued to be kept there until the mid-19th century). Small arms, ammunition, armour and other equipment were stored elsewhere within the Tower precinct, a succession of Storehouses and Armouries having been built for such purposes since the fourteenth century. From the mid-16th century bulkier items began to be stored in warehouses in
9243-515: The main, central repository until 1694, when a new gunpowder depot was established on the banks of the Thames at Greenwich Peninsula . The location was chosen both for reasons of safety (it was largely uninhabited marshland) and for convenience (because gunpowder barrels were invariably delivered by boat). The powder arrived at Greenwich from the manufacturers. Once there it was not only stored, prior to being despatched to wherever it might be needed, but
9360-584: The mid-17th century. It later expanded into a large-scale production facility, specializing in: Gunpowder manufacture was mostly kept separate of other operations (though some took place at Woolwich in the early years, inherited from the Wardrobe 's earlier activities at Greenwich Palace). Beginning in the 18th century, the Board began to purchase mills that had been established under private ownership: Ordnance Board activity at Ballincollig ceased in 1815; both it and Faversham were returned to private ownership in
9477-492: The mid-twentieth century. It also developed into a major manufacturing site (see below). During the Napoleonic Wars , concerns were expressed about the vulnerability of the nation's ordnance stores to attack from the sea. One response was the establishment of a Royal Ordnance Depot at Weedon Bec , well away from the coast in Northamptonshire: a sizeable complex of storehouses and gunpowder magazines constructed along
9594-559: The nearby Minories and cannons were proof-tested on the ' Old Artillery Ground ' to the north. Within the Tower, the New Armouries of 1664 served the Board as a small arms store (it can still be seen today in the Inner Ward). The vast Grand Storehouse of 1692 served not just as a store, but also as a museum of ordnance, precursor to today's Royal Armouries . (It was destroyed (along with its contents, some 60,000 objects) in
9711-647: The new artillery companies (which became the Royal Regiment of Artillery from 1722) now provided troops for this purpose; before long, they were also providing guns and heavy artillery for forts and garrisons around the country and indeed across the Empire. In addition, the Artillerymen did on-site work at the Arsenal and at other Ordnance Board facilities, from preparing fuses and proving weapons to providing
9828-403: The numbers of staff increased over time as a result. When the observatory was founded in 1675, one of the best star catalogues was Tycho Brahe 's 1000-star catalogue from 1598. However, this catalogue was not accurate enough to determine longitudes. One of Flamsteed's first orders of business was creating more accurate charts suitable for this purpose. One of the noted charts made at Greenwich
9945-412: The observatory at his own personal cost. Flamsteed House, the original part of the Observatory, was designed by Sir Christopher Wren , probably assisted by Robert Hooke , and was the first purpose-built scientific research facility in Britain. It was built for a cost of £520 (£20 over budget; equivalent to £99,000 in 2023) out of largely recycled materials on the foundations of Duke Humphrey's Tower ,
10062-454: The observatory was relocated elsewhere in stages in the first half of the 20th century, and the Greenwich site is now maintained almost exclusively as a museum, although the AMAT telescope became operational for astronomical research in 2018. There had been significant buildings on this land since the reign of William I. Greenwich Palace , on the site of the present-day National Maritime Museum,
10179-464: The precision of the instrumentation, and then there has to be accounting for precession , nutation , and aberration . Sources of error in the instrument have to be tracked down and accounted for to produce more accurate results. The transit circle makes two measurements; along with a clock, the time a star passed a certain point in the sky as the Earth rotates , and the vertical angle of the location of
10296-465: The principal Dockyards at Portsmouth ( Priddy's Hard ) and Devonport (Keyham Point), and at Chatham the Upnor facility was (eventually) expanded. These centres continued to grow, as the processes for refining and preserving gunpowder became more complicated and as new explosives began to be used, requiring their own storage and maintenance areas. In 1850, Devonport's magazine depot was moved from Keyham to
10413-668: The readings of the Magnetic and Meteorological Departments, and the Magnetic Observatory moved to Abinger in Surrey. Prior to this, the observatory had had to insist that the electric trams in the vicinity could not use an earth return for the traction current. After the onset of World War II in 1939, many departments were temporarily evacuated out of range of German bombers, to Abinger, Bradford on Avon , Bristol , and Bath , and activities in Greenwich were reduced to
10530-419: The rectifying of the tables of the motions of the heavens, and the places of the fixed stars, so as to find out the so much desired longitude of places for the perfecting of the art of navigation." He appointed John Flamsteed as the first Astronomer Royal. The building was completed in the summer of 1676. The building was often called "Flamsteed House", in reference to its first occupant. The scientific work of
10647-460: The same time the Tower, though still technically the Board's headquarters, was mostly given over to storage. In the mid-17th century the Board began to use land at Woolwich for storing and proving its guns. The land (known as The Warren ) was purchased in 1671 and in 1682 a thousand cannons and ten thousand cannonballs were transferred to Woolwich from the Tower and the Minories. At the same time,
10764-483: The seat of the Hare family. There are two Sites of Special Scientific Interest within the parish. Herstmonceux Park is of importance because of its wetland habitat and fen vegetation. It is the only known location of Milk Parsley ( Peucedanum palustre ) in the south-east. The second site, Pevensey Levels , lies partially in the parish. The site is of biological interest consisting of low-lying grazing meadows, hosting
10881-502: The senior technicians on the staff. The appointment of Master Gunner was first made as early as 1485, though it ceased after the establishment of the Regiment of Artillery in the 18th century; that of Chief Engineer was instituted in 1660. The Treasurer of the Ordnance was another important officer of the department, although he did not sit on the board. This office was instituted in 1670 (its duties having previously been discharged by
10998-567: The shield at its centre (it was previously used, along with the Board's motto, by the Royal Army Ordnance Corps ). The crest appears on the ensign of the Corps of Royal Engineers . The broad arrow was the Board's mark, used as such from the 17th century. Stamped on guns, papers, buildings and all kinds of equipment, it originally signified royal ownership. A proclamation of 1699 clarified its use on stores of war belonging to
11115-426: The star. The instrument can be used to plot the locations of stars, or alternately, with an accurate star chart, the time at the location of the instrument. The Shuckburgh telescope of the Royal Observatory in Greenwich was used for the 1832 transit of Mercury . It was equipped with a filar micrometer by Peter Dollond and was used to provide a report of the events as seen through the small refractor. By observing
11232-457: The transit in combination with timing it and taking measures, a diameter for the planet was taken. They also reported the peculiar effects that they compared to pressing a coin into the Sun. The observer remarked: I afterwards observed, that immediately around the planet there was a dusky tinge, making it appear as if, in a small degree sunk below the sun's surface;" British astronomers have long used
11349-460: The vicinity of naval dockyards. Bermuda's , begun in the 1830s, remains largely intact behind the dockyard fortifications; its magazines and storehouses are arranged around a small pool, where boats would arrive by way of a tunnel through the ramparts to be loaded with ammunition. For storage of gunpowder, a nearby fortified building was often used initially: the Square Tower at Portsmouth,
11466-721: The village, is a former site of the Royal Observatory, Greenwich . It is now home to the Bader International Study Centre of Queen's University, Kingston , Canada, and the area therefore enjoys an influx of Canadian and other international students each school year. The castle grounds are also home to the Observatory Science Centre and the Herstmonceux Mediaeval Festival. Buckwell Place was
11583-533: The world used it as their standard for mapping and timekeeping. The Prime Meridian was marked by a brass (later replaced by stainless steel ) strip in the Observatory's courtyard once the buildings became a museum in 1960, and, since 16 December 1999, has been marked by a powerful green laser shining north across the London night sky. Since the first triangulation of Great Britain in the period 1783–1853, Ordnance Survey maps have been based on an earlier version of
11700-417: Was Sir Bernard de Gomme . In 1802 the post of Inspector General of Fortifications was established, and this official took over supervision of these works. The Board also had responsibility for the building, upkeep and management of barracks and associated structures (except during a 30-year period, 1792-1822, when responsibility was transferred to a separate Barrack Office). Before this time, barracks were
11817-654: Was a British government body. Established in the Tudor period , it had its headquarters in the Tower of London . Its primary responsibilities were 'to act as custodian of the lands, depots and forts required for the defence of the realm and its overseas possessions, and as the supplier of munitions and equipment to both the Army and the Navy'. The Board also maintained and directed the Artillery and Engineer corps, which it founded in
11934-531: Was a petition to have another time ball established in Southampton also. The 1890s marked the addition of a new larger refractor, the 28-inch Grubb in the Great Equatorial Dome. Because the new telescope was longer than the old Great refractor, the new dome had to be bigger; thus the famous "onion dome" that expands beyond the diameter of the turret was established. For the tricentennial, it
12051-473: Was an active observatory, geographical coordinates were referred to a local oblate spheroid called a datum known as a geoid , whose surface closely matched local mean sea level. Several datums were in use around the world, all using different spheroids, because mean sea level undulates by as much as 100 metres worldwide. Modern geodetic reference systems, such as the World Geodetic System and
12168-588: Was by the Astronomer Royal James Bradley , who between 1750 and 1762 charted sixty thousand stars, so accurately his catalogues were used even in the 1940s. Bradley was the third Astronomer Royal , and his tenure started in 1742. In the early 19th century, the main positional devices were the Troughton Transit instrument and a mural circle , but after George Biddell Airy took over as Astronomer Royal in 1835, he embarked on
12285-407: Was completed on Greenwich hill. The establishment of a Royal Observatory was proposed in 1674 by Sir Jonas Moore who, in his role as Surveyor-General of the Ordnance , persuaded King Charles II to create the observatory, with John Flamsteed installed as its director. The Ordnance Office was given responsibility for building the Observatory, with Moore providing the key instruments and equipment for
12402-405: Was determined by marking the time a star of known location would pass through the aimpoint of the telescope. In a reverse case, this type of instrument was also used for making star charts. The stars whose position was known precisely enough for being used for time determination, were called "clock stars". By 1925, confusion about whether GMT was reckoned from noon or from midnight led (in 1928) to
12519-479: Was dropped by an operator; from 1852 it was released automatically via an electric impulse from the Shepherd Master Clock . The ball is still dropped daily at 13:00 (GMT in winter, BST in summer). The original time ball system was built by Messrs Maudslay and Field, and cost £180. The five-foot diameter ball was made of wood and leather. In the original ball system, it was hoisted by a rope up from
12636-423: Was formally constituted as the Board of Ordnance by Warrant of King Charles II; it consisted of five Principal Officers meeting under the chairmanship of the Master-General. At the same time it was given a new constitution ('Instructions') by Lord Dartmouth , the Master-General. These detailed Instructions continued, with relatively little change, to provide the working framework for the Board and its officers until
12753-634: Was installed in the Altazimuth Pavilion, from which the multi-purpose telescope is controlled by a computer system. Herstmonceux Herstmonceux ( / ˌ h ɜːr s m ə n ˈ z uː / HURSS -mən- ZOO , /- ˈ s uː / - SOO , or / h ɔːr s ˈ m aʊ n s iː z / horss- MOWN -seez ) is a village and civil parish in the Wealden District of East Sussex , England, which includes Herstmonceux Castle . The Herstmonceux Medieval Festival
12870-810: Was militarized in 1787, and named the Royal Military Artificers (they were then renamed the Royal Sappers and Miners 25 years later). The year after the demise of the Ordnance Board, the Sappers and Miners were fully amalgamated into the Royal Engineers, and at the same time the Corps moved from Woolwich to its present headquarters in Chatham . A Field Train Department was established in 1792 to serve as 'the field force element of
12987-548: Was not 0° but 0°00'00.417" (about 8 m) east. Besides the change of the reference line, imperfections of the surveying system added another discrepancy to the definition of the origin, so that the Bradley line itself is now 0°00'00.12" east of the Ordnance Survey Zero Meridian (about 2.3 m). This old astronomical prime meridian has been replaced by a more precise prime meridian. When Greenwich
13104-441: Was not chosen was because astronomers at the observatory would record when the Sun crossed the meridian at that time on that day. In rare occasions where the ball could get stuck due to icing or snow, and if the wind was too high it would not be dropped. In 1852, it was established to distribute a time signal by the telegraph wires also. The time ball was extremely popular with the public, chronometers, railways, mariners, and there
13221-653: Was officially known as the Royal Greenwich Observatory, Herstmonceux . Although the Astronomer Royal Harold Spencer Jones moved to the castle in 1948, the scientific staff did not move until the observatory buildings were completed, in 1957. Shortly thereafter, other previously dispersed departments were reintegrated at Herstmonceux, such as the Nautical Almanac Office , Chronometer Department,
13338-657: Was produced on a smaller scale, by specialist foundries mostly in the London area (in Houndsditch , Vauxhall , Southwark , at The Foundery in Moorfields and elsewhere). In time, the Board made moves to set up or purchase its own facilities. The Board's primary manufacturing site, and a key location for several of its activities, was the Royal Arsenal in Woolwich . Guns had been stored and proved there from
13455-426: Was revitalized with a fibre-glass dome; the old one made of papier-mâché and iron had been taken down. The telescope was installed by 1893, with 28-inch diameter glass doublet lens made by Grubb from Chance of Birmingham glass. The new dome was made by T. Cooke and Sons . This replaced a smaller drum-shaped dome. The Lassell two-foot reflector was a famous metal-mirror telescope that had been used to discover
13572-625: Was the Airy Transit Circle (ATC), which was used primarily from 1851 to 1938. It was agreed that the (Prime) "meridian line marked by the cross-hairs in the Airy Transit Circle eyepiece would indicate 0° longitude and the start of the Universal Day". (Note, however, that this Prime Meridian is obsolete; the ITRF Zero Meridian , which is more than 100 meters east, is the modern standard defining longitude.) The time
13689-545: Was the birthplace of both Henry VIII and his daughters Mary I and Elizabeth I ; the Tudors used Greenwich Castle , which stood on the hilltop that the Observatory presently occupies, as a hunting lodge. Greenwich Castle was reportedly a favourite place for Henry VIII to house his mistresses, so that he could easily travel from the Palace to see them. In 1676 the main building of the observatory, now known as Flamsteed House,
